You can get a really nice shiny anodize finish, but it has to be done by a professional with the proper tools. It requires an acid dip immediately prior to the anno bath. The required acid dip is very dangerous because it gives off toxic vapors. Immediately following the bath, the part needs to be cleaned and then anodized quickly to prevent normal surface oxidizing that naturally occurs on aluminum. In order to perform these processes, the anodizer needs very controlled work areas and heavy duty equipment, which eliminates most back yard anodizers from the equation.
Except for the Automag in front, its usually the man behind the equipment that counts.
